6 November 2008"Particle physics is at a crossroads," said Chairperson Albrecht Wagner of the International Committee for Future Accelerators, in the opening moments of the ninth ICFA Seminar last Tuesday in Kavli Auditorium. "The Standard Model stands triumphant," Wagner said, "yet incomplete."

25 September 2008Bob Siemann, a central leader in SLAC accelerator research for seventeen years, passed away last week. His legacy to SLAC includes a strong academic research program in advanced accelerator research, and many grateful recipients of his rigorous and enthusiastic mentorship.

3 April 2008The latest issue of symmetry launches the next phase of the magazine's development. Our readers now use the magazine in different ways, and we are reaching a much larger audience. While readers are outspoken in wanting to keep the print magazine, many of them are now more comfortable reading online.

6 March 2008After the news about budget reductions, especially for ILC activities, in December last year in the UK and US, there was considerable discussion within SiD whether to have this meeting or not. In the end we decided to proceed as planned because the call for LOIs still exists and SiD wants to prepare an LOI.

Barbara Warmbein | 16 August 2007Like the rest of society, the ILC community is split into two categories: the early risers and the night owls. Workshop organiser Andrei Seryi considers himself a night owl. Nevertheless he is up at 5 and in the lab at 6 am many days per week these weeks, holding phone meetings with the rest of the world. Some hundred specialists are already extremely busy preparing for the ILC interaction region engineering design workshop, or IRENG07, at SLAC in September. Their goal: to have all the facts together to take important decisions for the ILC’s interaction region.

9 August 2007Clouds might be welcome during a drought, but you definitely don't want them in your beam pipes. Researchers around the world are working out how to keep a section of the proposed International Linear Collider—the positron damping ring—clear of electron clouds.

19 July 2007While other labs concentrate on developing superconducting cavities for the International Linear Collider (ILC), SLAC is focusing on the technology needed to power them. In addition to klystron, modulator and radio frequency (RF) distribution development, this effort includes a coupler program. A coupler is basically a coaxial transmission line that connects normal-conducting, air-filled, room-temperature waveguides to each superconducting, evacuated, super-cold accelerator cavity. The couplers are complex devices due to the various requirements imposed on them; they must convert the RF to a coaxial mode, transmit high power (~300 kW), be mechanically flexible for cool-down of one end to 2K (-271

Elizabeth Clements | 5 July 2007When the Accelerator Test Facility (ATF) group at KEK decided to upgrade their beam position monitor system in 2005, Marc Ross had a solution. Based at SLAC at the time, he was a longtime collaborator with KEK and familiar with the instrumentation systems used throughout Fermilab’s accelerator complex. In 2006, Ross became the head of Fermilab’s Technical Division and could see how to continue his initiated beam position monitor upgrade efforts at the ATF damping ring. Called Echotek boards, these digital signal processing based systems offer a higher resolution potential – a characteristic that allows physicists to see more details about the beam. As it turned out, Fermilab was willing to make several Echotek boards available for testing the ATF system. Hence a new collaboration was born.

Barbara Warmbein | 26 April 2007Interactions members now officially classify as a tribe: flocking round the warming fire against the Californian chill they shared a goat during their meeting at SLAC last week. But though food may be memorable during the meetings of the InterAction collaboration, discussions and strategic plans are even more important for the communication representatives of particle physics labs, universities and projects. LHC start-up, the future of ILC communication and the meaning of blogs were just a few of the topics on the agenda of the three-day meeting that brought together 16 core and about 10 extended members of the InterAction family. They welcomed two new faces: Rika Takahashi, who has just taken up her job as ILC communicator for Asia at KEK, and Romeo Bassoli from INFN.
